Benefits of technology

The invention is an illumination device that uses a special optical film to create a larger and more intricate illumination effect. This film surrounds the light guide and reflects the light out, making it appear as if there is more light than there actually is. This optical film also prevents the light guide from being scratched. The best imaging effect is achieved when the ratio of the optical film to the light guide is between 2 and 3. Overall, this device provides a more fantastical and realistically-sized illumination.

Problems solved by technology

With the popularization of the illumination device, monotonous illumination function cannot satisfy the demands of consumers anymore.
However, since an increasing rate of production cost of the illumination device 1 is much larger than an increasing rate of the diameter D of the light guiding core 10, to increase the diameter D of the light guiding core 10 does not satisfy the need of production cost.

Abstract

An illumination device includes a light guiding core, an optical film and a light emitting module. The optical film separately surrounds the light guiding core. A ratio of a diameter of the optical film to a diameter of the light guiding core is between 2 and 3. The light emitting module is disposed at one side of the light guiding core.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates to an illumination device and, more particularly, to an illumination device with an optical film separately surrounding a light guiding core.[0003]2. Description of the Prior Art[0004]So far illumination device is considered a necessity by a lot of people. With the popularization of the illumination device, monotonous illumination function cannot satisfy the demands of consumers anymore. Therefore, more and more illumination devices with illumination function and pleasing appearance have been developed. Referring to FIG. 1, FIG. 1 is a schematic diagram illustrating an illumination device 1 of the prior art. As shown in FIG. 1, the illumination device 1 comprises a light guiding core 10, a light emitting module 12 and a base 14. The light guiding core 10 is disposed on the base 14. The light emitting module 12 is disposed in the base 14 and located at one side of the light guiding core 10. Light em...
